Understanding Carbon Monoxide Leaks

You might be wondering, why would anyone have a case of leaked carbon monoxide (CO) in their home? Well, the truth is, CO is a sneaky little gas that often goes unnoticed. It's produced during the incomplete combustion of fuels such as gas, oil, wood and coal.

CO leaks can pose serious risks to your health and safety, so it's essential to understand how they can occur in your home. Here are some common reasons why you might experience a case of leaked CO:

Faulty Appliances

Appliances such as gas stoves, water heaters, furnaces, and boilers can produce CO if they are malfunctioning or not properly maintained. Any fuel-burning appliance can be a source of potential leaks if it isn’t functioning as intended.

Blocked Vents or Flues

Vents and flues that carry combustion gases outside can become obstructed by debris, animal nests, or snow. This blockage can prevent CO from being vented outside, leading to dangerous buildup inside your home.

Improper Installation

If your appliances are not installed according to manufacturer guidelines or local building codes, they may not vent properly. For instance, a gas fireplace or furnace needs to have adequate venting to prevent CO leaks.

Running Engines Indoors

Operating vehicles, generators, or other engines inside garages or enclosed spaces can cause dangerous CO accumulation, especially in poorly ventilated areas.

Use of Gas-Powered Tools Indoors

Gas-powered lawn mowers, generators, or grills should never be used indoors, as they can release significant amounts of CO into the air.

Chimney Issues

Blocked or damaged chimneys can prevent smoke and gases from escaping, leading to CO buildup in living spaces.

Older or Aging Equipment

Older appliances may not function as efficiently or safely as newer models. Over time, wear and tear can lead to leaks or malfunctions that allow CO to seep into your home.

Environmental Factors

Atmospheric pressure changes or extreme weather conditions can affect how gases are vented, potentially leading to leaks.

Carbon Monoxide Poisoning 

Symptoms of CO poisoning can often mimic those of the flu – headaches, dizziness, and fatigue – making it all the more dangerous. If left unchecked, high levels of carbon monoxide can lead to serious health issues or even be fatal.

That’s where carbon monoxide detectors come into play. These life-saving devices are your first line of defense against this silent intruder.
